No problem with question, Tracy. I posted to remind myself of what happened so I don't forget, and also to help others who may face similar situations.
General rule of thumb I go by is to harvest 25 pounds of LMB per acre per year. For me, that's in the 200 to 250 LMB range, considering my average harvested fish is probably around 3/4-7/8 pound. Some are bigger, of course, but some are smaller, too. Try to focus on skinny fish, mostly males. I'd already harvested 139 before the electro harvest, so 56 more put me close to target.
If fish relative weights aren't great, I may harvest more. If RW looks good, I may harvest less. Electro guy told me that I probably have done enough now, bass are definitely healthier and not so abundant as to cause issues. Okay to take out really thin fish, but not absolutely necessary.
Somehow he could tell male from female LMB and did not harvest any females in good shape, even if less than 12 inches. Males got ruder treatment, but then we live in a feminist era.
I think part of his recommendation was based on how well the CNBG were doing, from YOY to bigguns. I feed, plus I grow some in a forage pond, which helps. Interestingly, the YOY CNBG moved to the rocks on the dam after their former home, the bushy pondweed, was knocked back. Lots for predators to eat, even though they must chase more than they should.
You're right about HSB, though they did see some nice ones. I'll harvest a few by hook & line this fall.
